#12031: GHCi segfaults on Windows when compiling C code using extern-declared variable -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Phyx- Type: bug | Status: merge Priority: high | Milestone: 8.0.2 Component: Runtime System | Version: 8.0.1 (Linker) | Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 | (amd64) Type of failure: GHCi crash | Test Case: T12031 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2316 Wiki Page: | -------------------------------------+------------------------------------- Comment (by Phyx-): @bgamari, you need to merge ae7e9cb574801954c7769c210829b06193fa72ea as well as this fixes the Ticky format specifiers. Currently that GHC-8.0 branch doesn't build with validate settings due to it. Also the following need to be applied {{{ diff --git a/rts/Linker.c b/rts/Linker.c index 8e00b92..82a37c8 100644 --- a/rts/Linker.c +++ b/rts/Linker.c @@ -4102,13 +4102,13 @@ ocGetNames_PEi386 ( ObjectCode* oc ) if (globalBssSize > 0) { bss = stgCallocBytes(1, globalBssSize, "ocGetNames_PEi386(non-anonymous bss)"); - addSection(§ions[oc->n_sections-1], + addSection(&oc->sections[oc->n_sections-1], SECTIONKIND_RWDATA, SECTION_MALLOC, bss, globalBssSize, 0, 0, 0); IF_DEBUG(linker, debugBelch("bss @ %p %" FMT_Word "\n", bss, globalBssSize)); addProddableBlock(oc, bss, globalBssSize); } else { - addSection(§ions[oc->n_sections-1], + addSection(&oc->sections[oc->n_sections-1], SECTIONKIND_OTHER, SECTION_NOMEM, NULL, 0, 0, 0, 0); } }}} This will make It compile, but the test isn't giving any output, have to look into that. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12031#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
